Toggle

Toggle switches things on and off.

Basic Usage

To implement the Toggle component, you need to import it first:

import { Toggle } from '@react-ui-org/react-ui';

And use it:

React.createElement(() => {
  const [studioQuality, setStudioQuality] = React.useState(true);
  return (
    <Toggle
      checked={studioQuality}
      label="Listen in studio quality"
      onChange={() => setStudioQuality(!studioQuality)}
    />
  );
});

See API for all available options.

General Guidelines

• Use the toggle only for boolean (true/false) input with an immediate effect (without confirmation). To toggle things on or off in forms that require to be submitted by a button, use rather the CheckboxField component.

• Use positive wording for the toggle label, so that it's clear what will happen when the user turns on the toggle. Avoid negations such as “Don't send me any emails” which would mean that the user needs to turn the toggle on in order for something not to happen.

• Only make the Toggle's label invisible when there is another visual clue to guide users through using the input.

• When a short label is not enough, use help texts to guide users before they enter anything.

• Use clear, calm error messages when there's a problem with what they entered.

• The toggle is designed for switching things on and off. Don't use it to switch between two different things that cannot be described as on or off using a single label, e.g. different viewing modes. In such cases, consider using the ButtonGroup component.

Help Text

You may provide an additional help text to clarify what will be the impact of turning the toggle on or off.

React.createElement(() => {
  const [studioQuality, setStudioQuality] = React.useState(true);
  return (
    <Toggle
      checked={studioQuality}
      helpText={
        'Unrivaled audio quality. Uses the MQA audio format. '
        + 'Transfers a lot of data.'
      }
      label="Listen in studio quality"
      onChange={() => setStudioQuality(!studioQuality)}
    />
  );
});

Label Options

In some cases, it may be convenient to visually hide the toggle label. The label remains accessible to assistive technologies.

React.createElement(() => {
  const [studioQuality, setStudioQuality] = React.useState(true);
  return (
    <Toggle
      checked={studioQuality}
      isLabelVisible={false}
      label="You cannot see this"
      onChange={() => setStudioQuality(!studioQuality)}
    />
  );
});

It's also possible to display the label before the input:

React.createElement(() => {
  const [studioQuality, setStudioQuality] = React.useState(true);
  return (
    <Toggle
      checked={studioQuality}
      label="Listen in studio quality"
      labelPosition="before"
      onChange={() => setStudioQuality(!studioQuality)}
    />
  );
});

States

Validation States

Validation states visually present the result of validation of the input. You should always provide a validation message for states other than valid so users know what happened and what action they should take or what options they have.

React.createElement(() => {
  const [studioQuality, setStudioQuality] = React.useState(true);
  return (
    <>
      <Toggle
        checked={studioQuality}
        label="Listen in studio quality"
        onChange={() => setStudioQuality(!studioQuality)}
        validationState="valid"
      />
      <Toggle
        checked={studioQuality}
        label="Listen in studio quality"
        onChange={() => setStudioQuality(!studioQuality)}
        validationState="warning"
        validationText={
          'Looks like you are connected over cellular network. '
          + 'Please make sure you know what you are doing.'
        }
      />
      <Toggle
        checked={studioQuality}
        label="Listen in studio quality"
        onChange={() => setStudioQuality(!studioQuality)}
        validationState="invalid"
        validationText="Please upgrade your plan to make this option available."
      />
    </>
  );
});

Disabled State

Disabled state makes the input unavailable.

<Toggle label="Disabled toggle" disabled />
<Toggle
  label="Disabled toggle, checked"
  disabled
  checked
/>

Forwarding HTML Attributes

In addition to the options below in the component's API section, you can specify any HTML attribute you like. All attributes that don't interfere with the API of the React component are forwarded to the root <input> HTML element. This enables making the component interactive and helps to improve its accessibility.

👉 For the full list of supported attributes refer to:

• <input type="checkbox" /> HTML element attributes
• React common props

Forwarding ref

If you provide ref, it is forwarded to the native HTML <input> element.
